Group the extra allocation parameters in a GstAllocationParams structure to make
it easier to deal with them and so that we can extend them later if needed.
Make gst_buffer_new_allocate() take the GstAllocationParams for added
functionality.
Add boxed type for GstAllocationParams.
Also register queries with a QueryType that allows us to check if the event is
sent in the right direction. Add a serialized query type because we will need
this for the allocation query.
Remove the QueryTypeDefinition stuff, it is not used anymore and we now use
custom queries and separate API for them.
Update defs.
Rename _do_simplify() to _simplify(). The name was introduced as a replacement
method for a deprecated method but we can now rename it again.
Fix some docs.
There isn't really any need to provide public API for that. It's not
used anywhere in practice, and we aim to provide an API that works
for GstCaps, not some kind of generic set manipulation API based on
GValue. Making this private also makes it easier to optimise this
later. We can always put it back if someone actually needs it.
Split out the registration of the metadata API and its implementation. Make a
GType for each metadata API. This allows us to store extra information with the
API type such as the tags.
Change the buffer API so that we can get the metadata using the API GType.
Change the query API so that we use the metadata API GType in the allocation
query instead of a string.
Update netaddress and unit tests
Flesh out the transform method. Add a type and extra info to the transform
function so that implementation can transform the metadata.
Remove the copy function and replace with the more generic transform.
Rename _is_writable() with _is_exclusive because the writability does not depend
on the amount of references to the memory object anymore.
Add accessor macros for the memory flags.
Rename the GstBuffer _peek_memory() method to _get_memory() and return a
reference to the memory now that we can do this without affecting writability
of the memory object. Make it possible to also make this function merge the
buffer memory.
Add methods to replace memory in a buffer. Make some convience macros for the
buffer memory functions.
Fix unit tests.
Add refcounting to the GstAllocator object.
Remove const from functions because the allocator is refcounted now.
Rename the vmethods for consistency
Expose the constructor for GstAllocator and add a destroy notify for the
user_data. This should make it possible to create allocators that are not
registered and shared globally along with the possibility to destroy them
properly.
Update defs with new symbols.
int and int64 ranges can now have an optional step (defaulting to 1).
Members of the range are those values within the min and max bounds
which are a multiple of this step.

We introduced our own when GLib didn't want to add a GType
for GError. But now that there is one, we can use GLib's
unconditionally and remove our version.
Which we had to add because GLib didn't have it
back in the day. Port everything to plain old
G_TYPE_DATE, which is also a boxed type. Ideally
we'd just use GDateTime for everything, but it
doesn't support not setting some of the fields
unfortuntely (which would be very useful for
tag handling in general, if we could express
2012-01 for example).
https://bugzilla.gnome.org/show_bug.cgi?id=666351
An extra application preset dir help to organize presets created for special
purposes. Fixes#660760
API: gst_preset_set_app_dir(), gst_preset_get_app_dir()
Add a new simple miniobject that is a combination of a GstBuffer, GstCaps,
GstSegment and other arbitrary info organized in a GstStructure. This object can
be used to exchange samples between an element and the application or for
storing album art in tags etc.
Better now than later in the cycle. These might come in handy:
sed -i -e 's/GstProbeReturn/GstPadProbeReturn/g' `git grep GstProbeReturn | sed -e 's/:.*//' | sort -u`
sed -i -e 's/GST_PROBE_/GST_PAD_PROBE_/g' `git grep GST_PROBE_ | sed -e 's/:.*//' | sort -u`
sed -i -e 's/GstProbeType/GstPadProbeType/g' `git grep GstProbeType | sed -e 's/:.*//' | sort -u`
No one uses this or should ever need to use it, since
the size is architecture-specific anyway. If normal
integers don't do, one should use 64-bit integers.
Remove gst_mini_object_register() and add a GST_DEFINE_MINI_OBJECT macro to
define a _get_type() function for the boxed miniobject.
Remove a bunch of custom _get_type() functions and replace them with the
miniobject macro.
Rename some _init method to _priv_*_initialize() like the rest of them.
Inspired by patch from Johan Dahlin and see bug #657603
Remove gst_pad_get_negotiated_caps(), it does not realy do what it says,
gst_pad_get_current_caps() returns the currently negotiated caps on the pad
correctly.
Make it possible to query the supported options of a bufferpool and enable
options. This is a bit more generic than the API to enable metadata. The purpose
is to make it possible to add new custom config options to the configuration of
the bufferpool when supported.
Also return the offset in a GstMemory block with the get_sizes() method. This
allows us to figure out how much prefix there is unused.
Change the resize function so that a negative offset can be given. This would
make it possible to resize the buffer so that the prefix becomes available.
Add gst_buffer_get_sizes() to return the offset and maxsize as well as the size.
Also change the buffer resize method so that we can specify a negative offset
to remove prefix bytes.
This allows to get the internal pad of ghostpads and
proxypads without using gst_pad_iterate_internal_links()
and is much more convenient.
The internal pad of a ghostpad is the pad of the opposite direction
that is used to link to the ghostpad target.
Remove the context again, adding an extra layer of refcounting and object
creation to manage an array is too complicated and inefficient. Use a simple
array again.
Also implement event updates when calling gst_pad_chain() and
gst_event_send_event() directly.
Remove pad_alloc and all references. This can now be done more efficiently and
more flexible with the ALLOCATION query and the bufferpool objects. There is no
reverse negotiation yet but that will be done with an event later.
Add a query to request allocation parameters and optionally a bufferpool as
well. This should allow elements to discover downstream capabilities and also
use the downstream allocators.
Allow for automatic merging of memory block in the _map function and automatic
freeing of the temporary memory.
Remove some unneeded functions.
Add possibility to force writable spanned memory.
Just like gst_caps_intersect, but adds a new parameter 'mode'
that allows selecting the intersection algorithm to use.
Currently we have GST_CAPS_INTERSECT_MODE_ZIG_ZAG (default) and
GST_CAPS_INTERSECT_MODE_FIRST.
API: gst_caps_intersect_full
API: GstCapsIntersectMode
API: GST_CAPS_INTERSECT_MODE_ZIG_ZAG
API: GST_CAPS_INTERSECT_MODE_FIRST
https://bugzilla.gnome.org/show_bug.cgi?id=617045
GST_DISABLE_DEPRECATED should only affect visibility of declarations in headers,
not actually remove symbols. See GitDeveloperGuidelines and DeprecatingAPI
pages in wiki.
https://bugzilla.gnome.org/show_bug.cgi?id=402141
Add new functions to clarify how the caps are compared to the template caps of
the element factory. Improve the docs to point out the difference.
Deprecate: gst_element_factory_can_{src|sink}_caps
API: add gst_element_factory_can_{src|sink}_{any|all}_capps
https://bugzilla.gnome.org/show_bug.cgi?id=402141
Use a GstStructure to provide the pool with the right configuration. Also
provide some helper methods to configure such a structure.
don't pass the config in alloc_buffer, pool implementation will already have
parsed it during set_config.
Update defs
Make separate api for getting and adding metadata. This allows us to pass extra
parameters to the init functions when creating metadata, which is needed for
specific API implementations.
Add beginnings of memory metadata.
Add first implementation of arbitrary buffer metadata. We use a simple linked
linked of slice allocated metadata chunks. Future implementations could use
something more performant.
Add get, remove, iterate methods to handle the metadata.
Add function that (unlike the GLib equivalent) also accepts paths that
aren't absolute and will clean up relative markers such as ./ and ../
before forming a URI.
Fixes warnings with e.g. filesrc location=foo ! typefind caused by the
recent switch to g_filename_to_uri(), but also actually creates valid
URIs for the first time.
Windows code paths could need some more work, e.g. we don't clean up
the relative markers there for now (because path could have \ and /
as separators).
API: gst_filename_to_uri()
The new request_new_pad_full vmethod provides an additional caps field,
which allows elements to take better decision process.
Also, add a gst_element_request_pad() function to allow developers to be
able to specify which pad template they want a pad of.
Convert gstutils to use that new method instead of the old one when more
efficient.
This is useful for being able to request pads in a more flexible way,
especially when the element can provide pads whose caps depend on
runtime configuration and therefore can't provide pre-registered
pad templates.
API: GstElement::request_new_pad_full
API: gst_element_request_pad
https://bugzilla.gnome.org/show_bug.cgi?id=637300
Adds 2 variants for the gst_date_time_from_unix_epoch function,
one for UTC and another for local time.
API: gst_date_time_new_from_unix_epoch_utc
API: gst_date_time_new_from_unix_epoch_local_time
Fixes#653031https://bugzilla.gnome.org/show_bug.cgi?id=635031
Add _set_value() variants that take ownership of the value passed
instead of making a copy of the value. This is useful for setting
values to things that aren't refcounted (e.g. GValueArrays or
strings or string arrays, etc.).
API: gst_structure_take_value()
API: gst_structure_id_take_value()
https://bugzilla.gnome.org/show_bug.cgi?id=629831
Add a GstStructure to GstElementClass and GstElementFactory. Add setters/getter.
Handle it in the registry code. Print items in gst-inspect.
Fixes#396774.
API: gst_element_class_set_meta_data(), gst_element_factory_get_meta_data_detail()
Added a new query type to retrieve informations about the areas of the
media currently buffered. See bug 623121.
API: gst_query_add_buffering_range
API: gst_query_get_n_buffering_ranges
API: gst_query_parse_nth_buffering_range

This allows removing structures from caps without them being freed. Helpful when
plugins need to move around structures without having to do an expensive structure
copy.
API:gst_caps_steal_structure
https://bugzilla.gnome.org/show_bug.cgi?id=621527
gst_event_new_sink_message()
gst_event_parse_sink_message()
This event is used for sending a GstMessage downstream and synchronized
with the stream, to be posted by the sink once it reaches the sink.
Fixes bug #602275.
gst_util_greatest_common_divisor()
gst_util_double_to_fraction()
gst_util_fraction_to_double()
Using these instead of going over GValue has much lower overhead.
Also add float<->fraction transform functions for GValue.
This returns the internal feature list cookie, which changes every
time a feature is added or removed. This can be used by elements
to check if they should update their cached feature lists.
In most places in core and baseclasses we just need the caps to do caps-
intersections. In that case ref'ed caps are enough (no need to copy).
This patch also switches the code to use the new functions.
API: gst_pad_get_caps_refed(), gst_pad_peer_get_caps_refed()
Often we don't need the result of the intersection. Add a variant that only
tries to intersect. It can break out earlier and does less GValue copying.
API: gst_caps_can_intersect()
Add a new macro GST_DEBUG_CATEGORY_GET to get a log category by name. This
allows plugins to use e.g. core categories like PERFORMANCE or CLOCK.
API: GST_DEBUG_CATEGORY_GET
Add new method to iterate a bufferlist without having to allocate an iterator.
Add convenience method for getting an item from the list based on the group and
index.
Remove redundant _do_data callback and method.
Update unit-tests and add some more for the new methods.
Add functions to create a new tag list and set tags in one go, which
is nice for use in combination with functions that take ownership of
the taglist, such as gst_event_new_tag() or gst_element_found_tags().
API: add gst_tag_list_new_full()
API: add gst_tag_list_new_full_valist()
Add a bunch of vararg getter convenience functions to complement
the vararg setter functions, and a basic unit test. Fixes#534208.
API: gst_structure_get()
API: gst_structure_id_get()
API: gst_structure_get_valist()
API: gst_structure_id_get_valist()
The first time one calls gst_element_factory_make(), gst recreates the plugin
feature and the element factory. As a side effect we ref the class to fill
in detail we already have filled from the registry cache. This patch changes
the behaviour to just update the existing entries. The factory is now attached
to the type and set in gst_element_base_class_init().
Add gst_segment_to_position() that converts a running_time to a position in the
segment. A faulty variant of this function is currently used in inputselector
but we'll need it for frame stepping too.
API: GstSegment::gst_segment_to_position()
Add new STEP event and methods for creating/parsing the event
Update design docs.
Add new STEP_DONE message and method to create/parse.
API: GstEvent::gst_event_new_step()
API: GstEvent::gst_event_parse_step()
API: GstMessage::gst_message_new_step_done()
API: GstMessage::gst_message_parse_step_done()
Add a start_time field and some methods. The start_time will contain the
running_time of when the element last went to paused. This time can be user to
report the position in PAUSED but also to do more correct clipping and
stepping later.
Add a gst_element_lost_state_full() with an extra argument to control
distribution of a new base_time. We will need this for flushing step
operations.
API: GstElement::gst_element_lost_state_full()
Reuse buffer code for bufferlists. Not sure if this measurably impacts performance
for the simple buffer case, if it does after doing some benchmarks, we can
decouple it later.
Fixes#572285
Remove the static function set on the TaskPool before _prepare() is called and
allow for assigning a function to a Task when we _push().
Update the examples
Two new log levels to dump FIXMEs into the log and to log data
in form of a hex dump (#578114).

This will be mostly useful in all elements that have some kind of internal
seek/index table. Currently almost all of them (or even all of them)
are using a linear search although the used array is already sorted,
wasting some CPU time without good reason.
Fixes bug #573623.
